3p=30
3 p is equal to 30

p+2=10
p plus 2 is equal to 10

p8=1
p over 8 is equal to 1

p+7=16
p plus 7 is equal to 16

4p=32

Answers

Answer 1
Answer:

Answer:

p + 2 = 10

(p)/(8) =1

4p = 32

Step-by-step explanation:

p - 3 = 5

p - 3 + 3 = 5 + 3

p = 8

3p = 30

3p ÷ 3 = 30 ÷ 3

p = 10

10 ≠ 8

p + 2 = 10

p + 2 - 2 = 10 - 2

p = 8

8 = 8

(p)/(8) =1

8((p)/(8)) =8(1)

8 = 8

p = 8

p + 7 = 16

p + 7 - 7 = 16 - 7

p = 9

9 ≠ 8

4p = 32

4p ÷ 4 = 32 ÷ 4

p = 8

8 = 8

A cylinder has a base diameter of 10cm and a height of 14cm. What is its volume in cubic cm, to the nearest tenths place?

Answers

Volume of any cylinder = π times (radius)² times (height or length)

Radius of your cylinder = 1/2 of the diameter =5 cm

Volume = π (5 cm)² (14 cm) = 350 π cm³ = 1,099.56 cm³ (rounded)
diameter : \ d = 10cm \nheight : \ h=14 \ cm \n \nr=(d)/(2)=(10)/(2)=5 cm \n \nvolume \ of \ a \ cylinder \ is \ equal \n \nV= \pi r^2h \n \nV= \pi\cdot 5^2 \cdot 14 =3.14\cdot 25 \cdot 14 = 1099.0 \ cm^3 \n \n Answer : \ its \ volume \ is \ 1099 \  cubic \ cm

Tina wants to save money for school. tina invests $400 in an account that pay an interest rate of 7.5%. How many years will it take for the account to reach $8500? Round your answer to the nearest hundredth.

Answers

Here's the given:
P=$400
i=7.5%
A=$8500

The formula used for this problem is:
A = P(1+i)^t

Manipulating the equation to arrive at t, we have:
t = ln(A/P) / ln(1+i)

Plugging in values:
t = ln($8500/$400) / ln(1+0.075)
t = 42.26 years

b minus 3/4 = 7/10

Answers

b - 3/4 = 7/10
b = 3/4 + 7/10
b = 15/20 + 14/20
b = 29/20
b = 1 and 9/20
b - 3/4 = 7/10
add 3/4 to both sides to isolate the b
b = 7/10 + 3/4
b = 28/40 + 30/40
b = 58/40
b = 1  18/40
b = 1   9/20

Ryan was adding numbers on a number line. He started at –3 and then he added +2. He wrote that his answer was –5 . Is Ryan's answer reasonable?

A.
No, it is not reasonable because if you start at –3, you will move 2 spaces to the right and get –1.

B.
No, it is not reasonable because if you add two integers, you get a positive integer. The answer is +5.

C.
Yes, it is reasonable because if you start at –3, you will move 2 spaces to the left and get –5.

Answers

The answer is A because it is -1 because it would go to the right when you add two
